I have a UWP app published to the Store and works great. The latest version I submitted to the store worked fine in Debug and Release builds locally, it passes the Windows App Cert Kit tests, it passes the Store certification process but it crash at runtime when I (or everyone else) download it from the store. The Store's Health report gives me a useless (at least for me) stack trace. What I did to fix the issue was to submit a previous version and guess what... same errors, that submit was the previous, working version. Here is the stack trace from the Health report:

    [generate a crash dump](https://msdn.microsoft.com/en-us/library/windows/desktop/bb787181%28v=vs.85%29.aspx) on a PC where you downloaded the app and use [Windbg + PDE.dll](https://stackoverflow.com/a/28437625/1466046) to see the a better stack – magicandre1981 Jun 06 '18 at 14:24

It's hard to diagnose this issue by the above stack trace. You'd better open a support ticket. You will get 1:1 support on that. Please kindly note that your support ticket will be free if it is Microsoft's issue.

  • Hi Xavier. I did opened a ticket and this was the answer "This issue surpasses our support and would suggest to post your question on the Tech Forums to get advice from one of our technical advisors" ‍♂️ – Leisvan Jun 07 '18 at 19:05
  • Have you tried to sideload your app to see if it will crash when you generate package successfully? – Xie Steven Jun 12 '18 at 10:03
